Embodiment
Present invention is described in conjunction with Fig. 1 and Fig. 2, Fig. 2 is the structural representation of the embodiment of the invention, and the PIC16C745 that adopts MICROCHIP is as processor 202, integrated communication interface 201,8 A/D converters carry 8KB storer 209 (not showing among the figure) in the chip.Infrared emission network 205 and infrared reception network 206 adopt one group of tetrad, convenient production.The logic chip that decoding network 203 usefulness are common, electronic switch network 207 is selected basic amplifier circuit for use.Coordinate is given software processing by communication interface 201.
Fig. 1 is a program flow diagram of writing and drag screen operator according to the judgement that the inventive method is implemented.
Fig. 3 is the synoptic diagram of the embodiment of the invention.As shown in Figure 3, comprise X-axis emission/receiving tube array, be designated as 0-15 in order, and Y-axis emission/receiving tube array is designated as 0-11 in order, wherein dotted line is for the ease of be blocked a little coordinate of displaying.Suppose that predefined described first numerical value is 3 in the judgment means, predefined described second value is 12.
In situation 1, in the synchronization, the user has blocked the point that coordinate is A (2,1), B (3,1), C (4,1).Judgment means is at first calculated the distance that A point and B are ordered by coordinate order from big to small, and result of calculation is 1, and the distance between A point and the B point is less than described first numerical value, and therefore, judged result is that A point and B point are continuity points.Judgment means continues to calculate the distance between B point and the C point, and result of calculation is similarly 1, and B point and C point also are continuity points, therefore carry out and write operation, and storer is reset.
In situation 2, in the synchronization, the user has blocked the point that coordinate is A (3,4), B (4,4), C (8,4).Judgment means is at first calculated the distance that A point and B are ordered by coordinate order from big to small, and result of calculation is 1, and the distance between A point and the B point is less than described first numerical value, and therefore, judged result is that A point and B point are continuity points.Judgment means continue to be calculated the distance between B point and the C point, and result of calculation is 4, and promptly greater than 3, and because 3 less than described second value 12, therefore, B and C point are effective discontinuous points, and effective discontinuous some number adds 1 in the storer.At last, because effective discontinuous some number is 1 in the storer, therefore, drag the content of screen display according to the motion track of described discrete effective blocking-up point, and storer is reset.
In situation 3, in the synchronization, the user has been blocked the point that coordinate is A (1,8) and B (15,10).The distance that judgment means calculating A point and B are ordered, according to Pythagorean theorem, distance is approximately 14.14, promptly greater than described second value.Therefore A point and B point are Null Spot, do not carry out any operation, and processor are reset.
